Description

The fully differential $\overline{B}\to D^{\ast }(D\pi ,D\gamma ){\ell }^{-}{\overline{\nu }}_{\ell }$ angular distributions are considered to scrutinize the effects of the $B\to D^{(\ast )}$ form factor parametrizations.
The use of the angular coefficients to pin down deviations from SM is discussed, in particular concerning lepton flavour universality violation phenomena.
A possible connection between the tension in the inclusive/exclusive determinations of $|V_{cb}|$ and the $R(D^{(\ast )})$ anomalies is discussed.
